The U.S. Department of Energy (DOE) today announced the award of the Outfall 200 Mercury Treatment Facility (OF200 MTF) contract to APTIM-North Wind Construction JV, LLC. The value of the Firm-Fixed-Price contract is $91,770,489. The period of performance is for up to 4 years after issuance of the initial notice to proceed, inclusive of final cleanup of the premises.
Two proposals were received in response to the solicitation. There is no incumbent contractor for this work. Early site preparation activities were started by other contractors in December 2017.
The objectives of the OF200 MTF acquisition include the following:
- Safely construct the Outfall 200 Mercury Treatment Facility Headworks, Transfer Pipeline, and Treatment Plant;
- Conduct systems testing; and
- Turnover facility management responsibilities to an operating contractor.
Outfall 200, from which the facility is named, is a location on the Y-12 National Security Complex (Y-12) where the headwaters originate for the Upper East Fork Poplar Creek.
The OF200 MTF is a vital piece of infrastructure because it will help DOE’s Oak Ridge Office of Environmental Management (OREM) toward fulfilling its regulatory commitments to reduce mercury levels in the East Fork Poplar Creek and enable large-scale cleanup and demolition to begin at Y-12.
“This facility is a central component of our cleanup strategy at Y-12,” said OREM Manager Jay Mullis. “We are incredibly grateful for the support we’ve received from Congress that allows us to move forward with construction, and we are excited for the opportunities and progress this project will help us achieve at one of the nation’s most important national security sites.”
Y-12 was initially constructed in 1943 to enrich uranium as part of World War II’s Manhattan Project, but the site soon became an integral part of Cold War weapons production. The process that was used until 1963 to separate lithium for those operations required the use of thousands of pounds of mercury.
When complete, the new facility opens the door for the demolition of Alpha-4, Alpha-5, and Beta 4 — large, deteriorated, former mercury-use facilities dating to the 1940s. After their removal, OREM will remediate the soils beneath them.
The facility will limit and control potential mercury releases as crews take down those buildings and address the soils that may disrupt the mercury-contaminated area on the west end of Y-12. When operational, the facility will treat up to 3,000 gallons of water per minute and include a 2-million-gallon storage tank to collect stormwater.
It will be comprised of two components — a headworks facility and a treatment plant connected by a pipeline. The headworks facility will capture creek flow on the west end of Y-12, store excess stormwater collected during large rainfalls, remove the grit, and pump water through the pipeline to the treatment plant on the east side of Y-12. The treated water will then flow into the East Fork Poplar Creek.
